SUPPORTING DEVICE FOR SOUND-BOX ARMS AND HORNS OF TALKING-MACHINES.

Application filed December To all 107mm it may concern.

Be it known that I. ltonznrr L. tluasox. a eitizen ot' the United States. and a resident of Philadelphia. State of Pennsylvania. have invented eertain new and useful lmprovements in thtpporting lleviees tor Sound-Box Arms and torus of Talkingfllaehines. ot whieh the following is a full. elear. and eomplete disclosure.

More partieularly iny improvements relate to the deviees for supporting the hollow sound-hox earrying arm and horn in the hraeket seeured to the ease of a talking machine.

It is my ohjeot to provide a simple and ettieient eonstruetion hy whieh the support of the souud-hox earl-yin; arm in proper position is assured notwithstmnling irregularities in the hraeket due to springing ot the hraeket arms or other eauses. This ohjeet l aeeoniplisl hy supporting the sound ho. 1 ear ryinp; arm wholly iu the upper free end of the h'raelv'et on hoth a vertieal and horizontal axis hy means ol' a rotary sleeve supported on hall hearings in a soeket on the hraeket. and earryingr a ring pieee at its'lower end, in whieh the sound hox earrying' arm is mounted on horizontal pivots. The arm is thus Supported hy the hraeket wholly from the top through the rotary sleeve. whieh, heing mounted on hall hearings. may turn with very little trietion. The hall hearings are formed hy a series of halls supported on an annular shoulder in a sleeve earried hy the soeket pieee ot the hraeket. and engaged by a flange on the upper end ot the rotary sleeve. The upper end of the sleeve earried hy the hraeket soeket terms a soeketneee for the horn.

The eonstruetion is not only very eltieient for the purposes intended, hat is simple and inexpensive and the. parts may be easily assembled or taken apart.

In the aeeompanying drawings. Figure 1 is a side elevation of a. talking maehine eon strueted in aeeordanee with this invention;

. Fig.2 an enlarged side elevation partly in vertical section on line A.\ of Fig. 3, of a. portion of the same; Fig. 3 a transverse. vertieal seetion on line l ---B of Fig. 2; Fig. 4 an enlarged fragmentary side elevation of a portion of the same; and I ig. 5 an enlarged fragmentary seetional perspective of a portion of the same.

Referring to the drawings, the case a of Specification of Letters Patent.

lPatentetl May ltZ, ilttliitl 11, 1905. Serial No. 251.197.

the talking machine contains the motor -whieh drives the turn-tahle or reeord support eat-tying the record A bracket it is adjustahly seeured at its lower end to an arm 1 on the said ease o. and is provided at its upper end with a tuhular socket y. in whieh is tilted a tuhular sleeve 2'. The upper part ot the sleeve ireeeives the elhow m to whieh the horn u is seeure-d... v v

The sleeve [is formed with an annular oilset or shoulder j on the inside below the elhow soeket portion. Within the lower portion of the sleeve Lisa sleeve Z'. whieh has its top turned oven or flanged as at o to form with the annular oti'set or shoulder j 7 an annular soeket or way for a series of halls p. The sleeve is thus supported at the top on hall hearings within the sleeve 1' and may turn treely upon them. To prevent the halls heeonrinp hunehed together. pins (1 may he placed transversely through the tlange o in the sleeve The lower end of the sleeve 7. extends below the soeket and sleeve f and ea ri -ies a ring f whieh is seeured hy a set serew f. This ring has depending arms I f earrying pivots r r. in whieh is pivoted the head of the hollow arm (Z whieh earries sound hox e. The head of the hollow arm is upturned and curved as at s from the pivots as centers, and hetween this eurved end and the ring is interposed a tuhular pieee e having its under faee eomplementary to and resting on M the eurved end s. The top of the tuhular pieee e receives the lower extremity of the sleeve Z' and between the pieee e and ring is interposed a eushion 10 preferably of ruhher tithing. whieh enahles the piece e to yield slightly and thus prevents binding between its lower curved edge and the curved edge s of the hollow arm. In this eonstruetion it will he ohserved that the hollo arm cl, whieh earries the sound hox e, is supported on the hraeket wholly from the top on a vertical axis formed hy the hall hiarings between the sleeve Z' and the sleeve '1', on whieh it. may turn freely with minimum trietion. The arm (1 is also pivoted on a horizontal axis formed by the pivots 1 7 carried hy the rinp f secured to the rotary sleeve Z1. The hollow arln thus has both its horizontal and vertical axes formed in the upper free end of the bracket 71, and, consequently, will not he so liable to be thrown out of alineinent by anyirregularity or springing of the bracket 72, as if a rigid vertical axis were formed between the top of the bracket and its lower part.

The arm LZ may be rocked on the pivots 7' a to raise and lower the sound box. To secure the arm and sound box in raised position, while a record disk is being removed and replaced, a spring catch '0 may be carried'by one of the arms 1, adapted to engage a notch or recess a; on the upper end of the hollow arm.

What I claim as new and desire to secure by Letters Patent, is as follows 1. The combination with a bracket adapted to be attached at one end to the case of a talking machine, and having a tubular socket atits free end, a sleeve carried by said bracket-socket, and having its upper end formed a socket to receive the horn, a rotary sleeve supported within said first sleeve and having its lower end projecting beyond the lower edge of the bracket-socket, a ring piece carried by said projecting end of the rotary sleeve, and a hollow sound box carrying arm mounted on horizontal pivots carried by said ring piece.

2. The combination with a bracket adapted to be attached at one end to the case of a talking machine, and having a tubular socket at its free end, a sleeve carried by said bracket-socket, and having its upper end formed as a socket to receive the horn,

3. The combination with a bracket adapted to be attached at one-end to the case of a talking nnichine, and having a tubular socket at its free end, a sleeve carried by said brackct-socket, and having its upper end termed as a socket to receive the born, a rotary sleeve supported within said lirst sleeve, and having its lower end projecting beyond the lower edge of the brackct-sockcl, a ring piece carried by said projecting end of the rotary sleeve, a hollow sound-box carrying arm mounted on horizontal pivots carried by said ringpiece, and having its end upturned and curved, a tubular piece having a coinplen'icntary curved lower edge interposed between the ring piece and the upturned curved end ol the hollow arm, and a yielding cushion interposed between said tubular piece and ringpicce;

1-, The combination with a bracket adapted to be attached at one end to the case of a talking machine,'and having a tubular socket at its free end, a sleeve carried by said bracket-socket, and having its upper end formed as a socket to receive the'horn a rotary sleeve supported within said first sleeve on ball bearings and having its lower end projecting beyond the lower edge of the b '21Ck6i1-SOCk8lL, a ring piece carried by said projecting end of the rotary sleeve, and a horizontal pivots carried by said ring piece.

5. The combination with a bracket adapted to be attached at one end to the case of a talking machine, and having a tubular socket at its free end, a sleeve carriedby said tubular socket and formed with an internal annular shoulder, a seriesot balls supported by said shoulder, a rotary sleeve within the first sleeve having its upper end provided with a flange engaging said balls, a ring piece carried by the lower end of said rotary sleeve, and a hollow sound-box carrying arm mounted on a horizontal axis carried by said ring piece. (5. The combination with a bracket adapt l ed to be attached at one end to a fixed sup port and having a tubular socketat-its free end, of a sleeve carried by said bracket socket, said sleeve being provided with. an enlarged end forming a shoulder resting j against said bracket, a horn rotatably mounted within said enlarged end, a rotary j sleeve supported upon said shoulder within I said first mentioned sleeve, and a sound conveying arm depending from said rotary i sleeve, i 7. The combination with a fixed support, I of a bracket rigidly attached at one end to i said support, and having a tubular socket at its free end, of a sleeve carried by said i bracket socket, said sleeve being provided with an enlarged cpd forming a shoulder {resting upon the top of said l )rackct, and a horn rotatably mounted within said enlarged i end o't' said sleeve. l c H.
